Metaparticle Compiler

This compiler transforms the metaparticle domain-specific language into execution on various backends (e.g. Kubernetes)

Status

This documentation is woefully incomplete, but fortunately, this tool is an implementation detail.

Schema

The OpenAPI Schema for the metaparticle DSL can be found here
